Firefox Support Forum

I want to delete firefox logins info and to make sure passwords and logins are never stored. I go to passwords, open up menu, and the "remove all passwords" choice is greyed out. How can I get that choice it be valid and to impliment that operation?? And to never have these stored??

i recently lost some data i want to get back, and this may be my last attempt, but is it by any chance stored here? and if it is, how do i transfer it back to my regular cache/cookies/data/bookmark folders

Dear Anyone.

I've got Firefox 125.0.3 - but ALL Firefoxes have ALWAYS done this!

I've got 12 gig RAM. I've been browsing for - say - a couple of hours or so, I look at how much RAM I've got spare and it's down to about 2 gig. So I close Firefox via Task Manager and all my RAM comes back. Then I REOPEN Firefox and all the old tabs are restored - but this time around, hardly using any memory! Which tells me the hewge memory munch was unnecessary the time before.

Firefox has ALWAYS done this from day 1. Nobody's ever fixed it, through all these updates. I've got the latest version and it's STILL memory-munching. How do you stop it? It's just annoying because you can be using other software that crashes because it runs out of memory, because Firefox has munched all its memory for no reason.

This is just a question, I'm Asperger's, I sometimes sound like I'm asking a leading/angry question but I'm not. (Not this time anyway!) Is there a workaround for this memory-munching problem, is it ever going to be fixed or is it too deeply embedded into Firefox's programming TO be fixed?

Yours respectfully

Chris.

Some years ago I had to replace my PC and thought - Wonderful - just use sync to bring back all my tabs etc into the new PC...

The long and the short of it (in the past), was that Firefox decided that the new PC was the one to be synchronising source, and promptly removed all the apps/tabs etc. so sync was in line with the new PC - erasing all the app data. I understand there is no 'Master' sync account.

The question is, how can I stop Firefox initially migrating the Firefox app data in the wrong direction? I know that the app/tab data is currently still correct as my laptop still has all my apps etc. Is there some way to stop Firefox thinking the latest clean browser on the new PC has the correct (None) apps etc? Has the laptop to be logged-in and currently on-line before starting the new PC with Firefox? Is there a process to follow with a new 'un-synced' PC?

Sorry if I'm making things sound difficult, but don't want to loose everything which is currently correct and still these within sync data. It's maybe something that can't happen in these later versions of Firefox, but I want to be sure before logging in my new 'Blank' PC.

I'm having trouble using my bank's website. Sometimes I can't log on (error messages) or I can log on and can't use certain features. The bank is Regions. The site works with other browsers. Is there some setting on the latest Firefox that needs to be adjusted? The articles I've read don't help. Thanks.

Can you recommend some kind of extension thet will only check current icons for the bookmarks? Just that. I don't need duplicate bookmarks checker, inactice checker and God knows what else checker. Just icons, that's good enough for me.

Hello! I synced my browsing data yesterday by signing in to firefox account and reset my OS(window 10) to improve my laptop's speed. When I am trying to get back my browsing data back after resetting and installing firefox by signing in to my firefox account and pressing the Sync Now button then its not giving me my browsing data back. Why is it so? Need Help. Thank You!!

Hello,

I need your help because i can't find solution to problem. On my macbooks air m1 i experience a very annoying thing: Often while i'm scrolling on websites smooth scroll animation get choppy/sluggish for few moments and lagging. It's like animation is FPS dropping during the scroll. I tried lot of things on both device:

- tried without extensions - created new profiles - use without syncing data - disabling hardware acceleration (gets worst) - disable smooth scroll in settings (get worst) - completely remove firefox with AppCleaner and reinstall it - Reinstall macOS and just install firefox alone. I tried latest Ventura and Sonoma

I don't have clue why this happening but ruin user experience very bad. With Safari everything is fine and smooth. On my wife's device (macbook air m3) have same issue.

Do you have any idea how can i fix it?

When I download PDFs on my MacBook using Firefox (currently 124.0.2 (64-bit)), they are always blank - I have attached a screen shot.

But if I download the same PDF using Safari, it opens straightaway - 2nd screen shot.

Is there something I need to adjust in Firefox to allow PDFs to open?

Hi,

Some websites still managed to smuggle in popups despite all the blockings. I use as add-ons: privacy badger, no-script, ublock origin and recently tried popup blocker (strict) and even have the 'block pop-up windows' enabled. I also tried to fiddle around in ´about:config´ but nothing helps. I think it's a recent occurrence as I don't remember having this problem, let's say, a couple of months ago.

The funny thing is that this problem doesn't occur in opera-browser (in which I hardly use extensions).

The websites that this occurs are: arabicpost.net (a pop-up will occur about 10 sec after right-clicking a new tab). focus.de (a video pop-up will occur if there's a video in it). Again opera-browser blocks all of this. I expect there will be other websites to add in the future.

Please help. S.O.S. -> g.o.i.n.g..i.n.s.a.n.e!

Everything is gone….bookmarks, passwords, history on my desktop computer and I have no idea why. I opened Firefox and the home page was different and then noticed nothing was the same. I dl Firefox again, no help, same result. I do have my desktop synced to my iPad and laptop but I’m concerned they will import from the desktop and get wiped out. Is there a way to sync from the laptop to the desktop? I am at a complete loss on how to fix this. I do run a backup on this computer. Would that help? Restore point?

Many thanks,

Len

Hello

I want to use extension xpi's from a shared external folder over multiple Linux profiles. So i examined the profile folder and found extensions.json. Though i can't find any documentation to it's keys online.

There's "rootURI:" with a "jar:file://path/to/extension.xpi!/", so i tried just replacing the path with the shared one. Though i observed that just makes firefox replace the path with the current one. So i examined further and found the "location:" key with the default value "app-profile". So my guess is, there's other values for other usecases, right?

So, in summary, what i need is:

• documentation to extensions.json keys or possible values to "location" key.
• if that isn't intended/doesn't work, how i can achieve my goal otherwise.

And please don't suggest the sync feature, that doesn't work for my usecase.

In all instances, when I click on a link to view a document on a website, rather than simply pop up to view, the document is downloaded and I am required to save it to my computer. Something in the Firefox settings is preventing the pop-up view from occurring. Not certain where to reset in order to correct this. Please advise

HI, I have a Mac with El Capitan OS and Firefox 78.15.0esr. Recently I can´t open some websites: ChatGPT, Likendin, TunnelBear, Wester Union, etc. Before everything was working perfect. Please HELP! Thanks friends :) When I try to open this website, nothing happens, nor an error, sometimes in certain website it keeps retrieving and thats it.

Many thanks,

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.
